A judge set bond at $1 million Wednesday for a man who caused a massive evacuation when he told security screeners he had a bomb in his backpack at Jacksonville International Airport, authorities said.

Zeljko Causevic, 39, remained silent during his brief hearing before Duval County Court Judge Russell Healey. He was arrested and booked into jail early Wednesday on charges that include making a false report about planting a bomb or explosive and manufacturing, possessing, selling or delivering a hoax bomb, according to an arrest report.

Airport officials said Causevic told screeners he had a bomb in his backpack but they only found a luggage scale with a microchip inside, along with a remote control device he called a "detonator."

"The subject stated, 'I came to the security guard and said I got a bomb in here,'" airport spokesman Michael Stewart said, reading the arrest report. "The subject further explained that inside his camouflage backpack he a device which he said was 'suppoed to be a bomb but it's not.' He described the device as a luggage scale containing two flat round batteries and a microchip inside."

Another person was arrested after officials say he started acting suspiciously but authorities said he was not connected to Causevic.

"The second person was acting suspiciously, they were approached by the police and they were arrested for, I think the report says resisting arrest," Stewart said. "There was no connection with the other individual as determined in the interview by the arresting authorities."

Manuel Rivera, 35, faces a charge of resisting an officer without violence, his arrest report said. He was released Wednesday morning, authorities said.

Gentry said the pilots initially told passengers they didn't know what was going on.

While the delay was cumbersome and bothersome, Gentry said everyone on his plane remained calm. He said he was never really concerned for his safety, because the plane remained so far from the terminal.

Around 9:30 p.m., a bus arrived to take the passengers on Gentry's flight to a nearby hotel.
